timer 是 rxjs 的定时器操作符
export function RefreshTokenComp({
refreshTokenActor,
}: {
refreshTokenActor: RequestActor;
}) {
const [access$, updateAccess] = useAccessMgr();
const access = useObservable(access$) || {};
const { refresh_token, expireAt } = access;
const [refreshTokenRequest] = useRequest(refreshTokenActor, {
onSuccess({ arg }) {
updateAccess(fromOAuthToken(arg.data));
},
});
useEffect(() => {
if (!refresh_token) return;
const expiresIn = moment(expireAt).diff(moment(), "s") - 120; // token 过期前二分钟左右刷新
const sub = timer(expiresIn * 1000).subscribe(() => {
refreshTokenRequest({ refreshToken: refresh_token });
});
return () => {
sub.unsubscribe();
};
}, [refresh_token]);
return null;
}
